My jacuzzi tub must have a leak in it as it has caved in the ceiling in my basement. Now there is this horrible smell coming from my bathroom. I am thinking it is probably rotten drywall, but not sure since tile surronds the tub. Where do I start? I'm sure the seals were broken in the tub, then again, I'm a nurse, not a plummer. I want to try to fix this myself. Any idea's? Thanks!
